是否可以在另一个XAML块中包含一个XAML块? [英] Is it possible to include a block of XAML in another block of XAML?

问题描述

我有如下所示的XAML:

I have XAML that looks like this:

<Grid VerticalOptions="Start">
   <Grid.ColumnDefinitions>
      <ColumnDefinition Width="Auto" />
      <ColumnDefinition Width="*" />
   </Grid.ColumnDefinitions>
   <Label Grid.Row="0" Grid.Column="0" HorizontalOptions="Start" Text="Exclude Hidden" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="0" Grid.Column="1" HorizontalOptions="Start" Text="All cards except those tagged as hidden" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="1" Grid.Column="0" HorizontalOptions="Start" Text="Include Hidden" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="1" Grid.Column="1" HorizontalOptions="Start" Text="All cards including those tagged as hidden" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="2" Grid.Column="0" HorizontalOptions="Start" Text="Favorites" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="2" Grid.Column="1" HorizontalOptions="Start" Text="Only cards tagged as favorites" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="3" Grid.Column="0" HorizontalOptions="Start" Text="Hidden" Style="{StaticResource helpDetail}" />
   <Label Grid.Row="3" Grid.Column="1" HorizontalOptions="Start" Text="Only those cards tagged as hidden" Style="{StaticResource helpDetail}" />
</Grid>

代码出现在两页上.我想将其保留为XAML.

The code appears on two pages. I would like to leave it as XAML.

有没有一种方法可以将该XAML放入文件中，并将其包含在两个页面中的每个其他XAML中.请注意，我不想将所有内容都转换为C#，因为我有很多这样的实例.

Is there a way that I can put this XAML into a file and include it in the other XAML's for each of the two pages. Note that I don't want to convert everything to C# as I have many instances like this.

推荐答案

创建一个名为Templates的目录，然后创建一个新的View类MyCustomGrid，如下所示:

Create a directory called Templates, and then create a new View class, MyCustomGrid like so:

Templates/MyCustomGrid.xaml :

<?xml version="1.0" encoding="UTF-8"?>
<Grid xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="MyProject.Templates.MyCustomGrid">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Label Grid.Row="0" Grid.Column="0" HorizontalOptions="Start" Text="Exclude Hidden" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="0" Grid.Column="1" HorizontalOptions="Start" Text="All cards except those tagged as hidden" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="1" Grid.Column="0" HorizontalOptions="Start" Text="Include Hidden" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="1" Grid.Column="1" HorizontalOptions="Start" Text="All cards including those tagged as hidden" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="2" Grid.Column="0" HorizontalOptions="Start" Text="Favorites" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="2" Grid.Column="1" HorizontalOptions="Start" Text="Only cards tagged as favorites" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="3" Grid.Column="0" HorizontalOptions="Start" Text="Hidden" Style="{StaticResource helpDetail}" />
    <Label Grid.Row="3" Grid.Column="1" HorizontalOptions="Start" Text="Only those cards tagged as hidden" Style="{StaticResource helpDetail}" />
</Grid>

Templates/MyCustomGrid.xaml.cs

using Xamarin.Forms;

namespace MyProject.Templates
{
    public partial class MyCustomGrid : Grid
    {
        public MyCustomGrid()
        {
            InitializeComponent();
        }
    }
}

要在其他页面(即 MyPage.xaml )中使用它:

To use it in another page, ie MyPage.xaml:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:templates="clr-namespace:MyProject.Templates;assembly=MyProject"
    x:Class="MyProject.MyPage">

    <templates:MyCustomGrid />

</ContentPage>
